[build] Put integer type definitions into `integer-types.h'.
Refactor some of the `ftconfig.h' headers and template to move the definition of the FreeType integer types (e.g., `FT_Int16') to a common header file `freetype/config/integer-types.h'. * builds/unix/ftconfig.h.in, builds/vms/ftconfig.h, include/freetype/config/ftconfig.h: Split off integer type definition stuff to... * include/freetype/config/integer-types.h: ...this new file. * builds/unix/ftconfig.h.in: Control the definition of `FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro `FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto detection happens in `integer-types.h' as usual based on `INTXX_MAX' values. Otherwise the autoconf-detected values are used. * builds/unix/configure.raw (CPPFLAGS): Don't include path to `config' directory. Instead, ... (FT_CONFIG_STANDARD_LIBRARY_H): Use complete path.

|
||||
|
||||
Refactor some of the `ftconfig.h' headers and template to move the
|
||||
definition of the FreeType integer types (e.g., `FT_Int16') to a
|
||||
common header file `freetype/config/integer-types.h'.

* builds/unix/ftconfig.h.in, builds/vms/ftconfig.h,
|
||||
include/freetype/config/ftconfig.h: Split off integer type
|
||||
definition stuff to...
|
||||
* include/freetype/config/integer-types.h: ...this new file.
|
||||
|
||||
* builds/unix/ftconfig.h.in: Control the definition of
|
||||
`FT_SIZEOF_INT' and `FT_SIZEOF_LONG' with macro
|
||||
`FT_USE_AUTOCONF_SIZEOF_TYPES'. If these are not defined, auto
|
||||
detection happens in `integer-types.h' as usual based on `INTXX_MAX'
|
||||
values. Otherwise the autoconf-detected values are used.
|
||||
|
||||
* builds/unix/configure.raw (CPPFLAGS): Don't include path to
|
||||
`config' directory. Instead, ...
|
||||
(FT_CONFIG_STANDARD_LIBRARY_H): Use complete path.
